PK-4Exi junction box
The PK-4Exi junction box is used for piercing cables of self-contained circuits inside explosive atmospheres. It is a simple device.
It consists of a printed circuit board with regular terminals, embedded in a plastic or aluminum box with grommets. The number of grommets ranges from 1 to 4 and the type from PG9 to PG13,5.
When using a silicon box, grounding is required with water of min 4 mm²
